A ray of light while traveling from a denser to rarer medium grazes the separating surface. Express the critical angle in terms of the speed of light in the two media.

When a wave travels from a denser to rarer medium, then

Consider a ray of light passing from one medium to another. If the angle of refraction is less than the angle of incidence, will the speed of light in the second medium be less or more than that in the first medium?

A ray of light travels from an optically denser to rarer medium. The critical angle of the two media is C. The maximum possible deviation of the ray will be

What happens to the direction of ray of light if it travels from (a) a denser medium to a rarer medium (b) a rarer to a denser medium (c) perpendicular to the surface of separation of two mediums?

Ray of light bends as light travels from one medium to another.

How is the refractive index of a medium related to the speed of light ? Obtain an expression for refractive index of a medium with respect to another in terms of speed of light in these two media ?

A ray of light is incident from a denser to a rarer medium. The critical angle for total internal reflection is theta_(ic) and Brewster's angle of incidence is theta_(iB) such that (sintheta_(ic))/(sintheta_(iB))= eta=1.28 . The relative refractive index of the two media is

When a ray of light from air enters a denser medium, it :

When a ray of light travels from optically denser medium to optically rarer medium, it always bends towards the normal.
